National Security Assessment:
U.S. Defense Supply Chain Network – C4ISR Survey


The U.S. Department of Commerce, Bureau of Industry and Security (BIS), Office of Technology Evaluation, in coordination with the U.S. Department of Defense (DoD), Office of Manufacturing and Industrial Base Policy, is conducting a series of industrial base surveys of DoD’s supply chain network.  The principal goal of this effort is to provide DoD with a comprehensive sector-by-sector, tier-by-tier (S2T2) assessment of the defense supply chain. The results will be used in the budget process; to inform decision-making on industrial base sustainment, manufacturing technology, and other industrial base investments; and to support other supply chain and market research efforts.  Specifically, the DoD seeks to make informed decisions as the defense budget adjusts to the drawdown from two wars and to new fiscal realities – decisions that protect critical skills and industrial capabilities and that prepare the industrial base to meet future national security requirements.

The current survey emphasizes, but is not limited to, facilities that contribute products and services to the Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4ISR) supply chain.  Many facilities selected to participate in the survey do not directly supply the federal government, and many facilities involved at lower tiers of the supply chain would not characterize themselves as producers of C4ISR or even defense-related products or services.  Nevertheless, these subcontractor facilities make important contributions to our national defense.

All information submitted to BIS is protected as Business Confidential under provisions of the Defense Production Act (DPA) of 1950, as amended.  Survey responses are also exempt from Freedom of Information Act (FOIA) requests.  The information collected from all survey respondents cannot be published or disclosed, other than in aggregate form.
